Mariota stayed down for a moment then was walked off the field shaking his right hand. With only 24 seconds left in the first half, the training staff took Mariota directly into the locker room. Backup quarterback Blaine Gabbert came in to relieve Mariota and has remained in the game, which is in the fourth quarter with the Colts leading 31-3.
Mariota is officially listed as questionable to return to the game. He was sacked four times and threw for just 85 yards on on 10-of-13 passing.
Earlier in the game, Titans defensive coordinator Dean Pees was taken to a local hospital for observation after experiencing a medical issue in the press box.
